  • receivers associated with UWB transmitters would attempt to recover as much of the transmitted bandwidth as possible for information processing purposes. Accordingly, we propose to eliminate this prohibition for UWB transmitters, and seek further comment on this proposal. Other Matters Several proponents of UWB devices have questioned whether such devices can operate under the standards contained in 47 C.F.R. §§ 15.217-15.255. This would result in a transmitter that may have a fundamental emission bandwidth greater than one gigahertz operating under the standards developed for a narrowband signal, e.g., the 30 MHz available for radar systems operating at 5800 MHz under 47 C.F.R. § 15.245. These requests were submitted in an attempt to permit the manufacturers to avail themselves of the higher

  • addition, the LF spectrum is used by unlicensed devices. These systems do not have any allocation status, but are authorized to operate under our Part 15 Rules on an unprotected, non-interference basis with respect to all other users. Section 15.209 permits operation of authorized systems with field strengths of up to 4.9 microvolts/meter in the 9-490 kHz band. Additionally, Section 15.217 permits use of the 160-190 kHz band for general unlicensed operations limited to one watt total input power to the final radio frequency stage (exclusive of filament or heater power) with the length of the transmission line, antenna and ground lead not to exceed 15 meters. Emissions outside of the 160-190 kHz band must be attenuated by at least 20

  • of Wide Bandwidth Systems under the Existing Rules Proposal. In the Notice, we proposed specific regulations regarding the frequency of operation and emission levels that would apply to UWB devices. We expressed concern that UWB manufacturers would wish to operate their products under a combination of both the UWB regulations and the existing Part 15 regulations in 47 C.F.R. §§ 15.217-15.255. This would result in a transmitter that has an extremely wide bandwidth attempting also to operate under standards that were developed for narrowband operation. An example would be a UWB device that operates at 5800 MHz attempting to demonstrate compliance with 47 C.F.R. § 15.245 over the frequency range 5785-5815 MHz while demonstrating compliance with the UWB emission limits outside

  • considered sufficient to comply with the provisions of this Section. The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited. This requirement does not apply to carrier current devices or to devices operated under the provisions of Sections 15.211, 15.213, 15.217, 15.219, or 15.221. Further, this requirement does not apply to intentional radiators that must be professionally installed, such as perimeter protection systems and some field disturbance sensors, or to other intentional radiators which, in accordance with Section 15.31(d), must be measured at the installation site. However, the installer shall be responsible for ensuring that the proper antenna is employed so
